Expand description

@brief Process all remaining response data This uses an internal buffer to repeatedly receive, parse, and discard response data until complete data is processed. As no additional user-supplied buffer is required, this may be preferrable to esp_http_client_read_response in situations where the content of the response may be ignored.

@param[in] client The esp_http_client handle @param len Length of data discarded

@return - ESP_OK If successful, len will have discarded length - ESP_FAIL If failed to read response - ESP_ERR_INVALID_ARG If the client is NULL
